LAWRENCEVILLE, N.J., June 20, 2014 /PRNewswire/ -- Celsion Corporation (Celsion) (NASDAQ: CLSN), an oncology drug development company, today announced the completion of the acquisition by Celsion of substantially all of the assets of EGEN, Inc. (EGEN), a privately-held biopharmaceutical company focused on the development of nucleic acid-based therapeutics for the treatment of cancer and other difficult to treat diseases. The acquisition includes EGEN's Phase Ib DNA-based immunotherapy product candidate EGEN-001 and its therapeutic platform technologies, TheraPlas for delivery of DNA and mRNA, TheraSilence for delivery of RNA, and RAST for Cell Enabled Expression and Secretion of RNA.

"Completing the acquisition of EGEN marks a defining event for Celsion, as it brings together leading-edge assets and capabilities with the opportunity to not only advance medicine and patient care in cancer and other serious diseases, but create long-term value for our shareholders," said Michael H. Tardugno, Celsion's President and Chief Executive Officer. "Now, all at once a fully integrated development company with assets and capability from feasibility to commercialization, we look forward to advancing our pipeline of chemotherapies, immunotherapies and DNA or RNA-based therapies in the lab and in ongoing or planned Phase III, II and I studies. Our strong balance sheet provides us with an impressive internal development runway, as well as allows us to develop collaborative partnerships leveraging the power of our multiple platforms."

Under the terms of the agreement, CLSN Laboratories, Inc., a wholly-owned subsidiary of Celsion (CLSN Laboratories), acquired substantially all of the assets and assumed certain specified liabilities of EGEN. At the closing, Celsion issued $8.5 million worth of common stock, representing approximately 15.8% of its outstanding shares, paid approximately $3.0 million in cash to EGEN, and holds back $2.1 million worth of common stock until August 2, 2016 for expense adjustment and certain indemnification claims of Celsion. In addition to the upfront payment, a total of $30.4 million in future milestone obligations are payable to EGEN based on the successful completion of certain clinical development and licensing milestones.

The combination of Celsion and EGEN will create a fully-integrated, oncology-focused research and development company with a multi-phase clinical pipeline, platform technologies for the discovery of novel, nucleic acid-based immunotherapies and other anti-cancer DNA/RNA therapies, and expertise from bench to bedside. The transaction brings to Celsion EGEN's lead, Phase Ib clinical candidate, EGEN-001, an IL-12 plasmid immunotherapy encased in a nanoparticle delivery system, as well as three technology platforms, TheraPlas, TheraSilence, and RAST for Cell Enabled Expression and Secretion of RNA.

The transaction complements Celsion's lead development candidate, ThermoDox®, a proprietary heat-activated liposomal encapsulation of doxorubicin, currently in a pivotal, double-blind, placebo-controlled, global Phase III trial (the OPTIMA Study) in primary liver cancer.

CLSN Laboratories has retained all EGEN employees and will be based in Huntsville, Alabama, where Celsion also plans to consolidate all of its analytical service and laboratory functions.

ThermoDox® is a proprietary heat-activated liposomal encapsulation of doxorubicin, an approved and frequently used oncology drug for the treatment of a wide range of cancers. ThermoDox® is being evaluated in a Phase III clinical trial for primary liver cancer and a Phase II clinical trial for recurrent chest wall breast cancer. Localized mild hyperthermia (39.5 - 42 degrees Celsius) created by radiofrequency ablation (RFA) releases the entrapped doxorubicin from the liposome. This delivery technology enables high concentrations of doxorubicin to be deposited preferentially in a targeted tumor.
